A fake IW327010 is a counterfeit copy of the IWC Pilot's Watch Mark XVIII Edition "Le Petit Prince," a 40 mm stainless steel pilot's watch with a sunburst blue dial and the caliber 35111 automatic movement. Because the real reference is simple in design, counterfeiters can get the silhouette close with a cheap case and dial. The tells sit in the small details: printing weight, date window shape, crown feel, crystal reflections, case back markings, and the strap hardware.
Why the IW327010 Is Copied So Often
The Mark XVIII is a clean three hand pilot's watch. There is no chronograph, no date complication beyond a simple aperture, and no exotic material to imitate. That makes it cheap to fake and hard to spot from across a table. The genuine watch also shares its case architecture with other Mark XVIII references, so a counterfeiter only needs one case design to serve several models.
That is why the fake IW327010 market splits into two tiers: low grade copies sold on marketplaces, and higher grade copies that get the case diameter right but still miss the dial execution and the movement finish.
Specs a Fake IW327010 Usually Fails
Know the genuine numbers before you inspect anything. Counterfeiters rarely match all of them at once.
- Case diameter around 40 mm in stainless steel, with a modest thickness for an automatic pilot's watch
- Blue dial with a sunburst finish that shifts from deep navy to brighter blue as light moves across it
- Caliber 35111 automatic movement, roughly 42 hours of power reserve, running at 28,800 vibrations per hour
- Sapphire crystal with anti reflective coating on both faces
- Water resistance rated to 6 bar (about 60 meters), not the 100 or 200 meters fakes often advertise
- Soft iron inner case for magnetic protection, a detail cheap copies skip
If a listing claims 200 meters of water resistance or a display case back, that alone is a mismatch with this reference.
Dial, Printing, and the Date Window
The dial is where most fakes fall apart under a loupe or a phone macro shot.
- Text weight: Genuine IWC printing is thin, crisp, and consistent. Fakes show thicker strokes, fuzzy edges, or uneven spacing between the logo and the model text.
- Sunburst finish: Look for a smooth radial grain that reacts to light. Cheap dials look flat, grainy, or painted rather than brushed.
- Date window: The aperture should be cleanly cut with sharp corners and a properly centered date wheel. Crooked dates and rounded corners are common on copies.
- Numerals and markers: Applied indices should sit level and reflect light with sharp edges. Painted or glued markers sit lower and catch light differently.
- Hands: The pilot's hands should be matte and evenly filled. Look for overspray, bubbles, or a rough edge where the fill meets the metal.
Case, Crown, Crystal, and Lume
Case finishing is the second biggest giveaway. Genuine IWC cases mix brushed surfaces with polished bevels, and the transition between them is sharp and even. Counterfeits tend to round off those edges or polish surfaces that should be brushed.
Check the crown next. It should turn with light, consistent resistance, and it should screw down smoothly without grit. A wobbly crown, a stem that feels loose, or threads that catch are warning signs. On the crystal, genuine double sided anti reflective coating nearly removes reflections at an angle. Fakes often have heavy blue or purple reflections instead.
For lume, charge the watch under a light and compare. Genuine lume glows evenly across all markers and fades at the same rate. On a fake IW327010, one marker often glows brighter than the others, or the glow dies within minutes.
Movement and Case Back
This reference uses a solid steel case back, so you cannot inspect the movement through the watch. That protects sellers of fakes, which is why the case back itself deserves close attention.
- Engraving should be deep, sharp, and evenly spaced, with the reference number, case number, and model text aligned as a set
- The case back should seat flush with no gap at the edge, and it should not spin loosely on the threads
- If a watchmaker opens the watch, the caliber should show Geneva style finishing, correct rotor engraving, and no plastic movement ring
- Timing on a timegrapher should be stable, with a healthy amplitude and low beat error
Ask the seller for the case number and reference number, then verify both against the official IWC records for this reference before money changes hands.
Strap, Buckle, and Packaging
The genuine watch ships on a leather strap with a signed pin buckle or folding clasp. Stitching should be tight and straight, the leather edges should be sealed, and the buckle should carry clean engraving rather than a stamped logo.
Boxes and papers are the easiest items to fake, so treat them as a bonus rather than proof. A correct box with the wrong dial is still a fake IW327010. Focus on the watch, then use the paperwork to confirm what you already see.
How to Verify Before You Buy
- Compare the listing photos against official product images of the reference, side by side at the same angles.
- Ask for macro shots of the dial text, date window, crown, and case back engraving.
- Request a movement photo or a timegrapher reading from an independent watchmaker.
- Check the seller's history and prefer a service that offers authentication.
- Walk away from any price that sits far below the current market range for a complete example.
If several details feel off, trust that feeling. The strongest sign of a fake IW327010 is not one flaw. It is a group of small imperfections that never appear together on a genuine IWC.
